PROBLEM TO BE SOLVED: To provide a powder type cement mineral based quick setting agent which is added to cement for the work of spraying concrete to improve adhesion and accelerate strength development by quick hardening.;SOLUTION: The cement mineral based quick setting agent is composed of a mixture containing a calcium aluminate powder, sodium carbonate, anhydrous gypsum, slaked lime and sodium aluminate. The calcium aluminate powder is produced by: mixing quicklime, bauxite and alumina by-product and melting in a melting furnace; drying through a water cooling process where the molten product to be placed in a rotary cooler is ejected witb compressed air and water to be quickly cooled; and performing a crushing process.;COPYRIGHT: (C)2013,JPO&INPIT
